The Mares Avanti QUATTRO 4X represents the evolution of one of diving’s most trusted fins, now re-engineered with modern materials and refined ergonomics. Whether you prefer flutter, frog, or back kicks, this open-heel fin ensures efficient propulsion with less effort, making it ideal for divers of all skill levels.

Its three-material construction blends flexibility with responsiveness — producing powerful thrust while reducing strain on your legs. The optimized foot pocket combines soft thermoplastic rubber for comfort and reinforced lower sections for stability, ensuring every kick transfers energy directly into forward motion.

The 4-channel blade increases water flow and propulsion efficiency, while stabilizing side ribs with overmolding maintain blade shape and reduce side slip. Comfort is further enhanced with an anatomical heel pad that relieves tendon stress and an elastic bungee strap for quick donning and doffing, even with gloves.

Safety is built-in with an anti-slip sole, providing secure footing on boats or rocky entries. Each pair comes in a reusable mesh bag, reducing single-use plastic and making post-dive transport and drying effortless.

Available in XS, S, R, and XL, the Avanti QUATTRO 4X offers a tailored fit for every diver, backed by Mares’ proven performance heritage.
